wI1vnow-sAsR.oRRRATI1ve DEVICE. I

To all whom it may concern: V Be it known that I, OR B. GILB Rna citizenof the United States, residing at Fort Leavenworth, in the county ofLeaven- 5 worth and State of Kansas, have invented certain new anduseful Improvements in Window-Sash-Operating the following is aspecification. v My invention relates to window sash opcrating devices,and my object is to provide a simple and efficient device of thischaracter whereby the upper sash can be raised and lowered without theoperator touching said sash. By the use of my device, the upper sash canbe operated without having to first raise. the lower sash in order 'tovgain access to the meeting rail of the upper sash for thepurpose ofraising orlowering the latter. 3 l vInorder that the inventionmay befully understood, reference will now be made to the accompanyingdrawings, in which; v

Figure l is a broken front elevation of a Window frame with its sashesequipped'with the invention. I c

Fig. 2 is an enlarged broken vertical section on line H of Fig. 3. V

Fig.3 is a plan view.

Fig. 4 is an irregular broken vertical section on line IV of Fig, 2,with the lower sash sash and its respective roller added.

F ig. 5 is a detail perspective view of a bracket for supporting theright end of the rollers.

85 Fig. 6 is adetail bracket for supporting the left end of the rollers.

Fig. 7 is an elevation of a cam roller and its bracket, employed incarrying out the 4 invention.

Referring now in detail to the various parts, A designates a windowframe of ordinary construction, excepting that the four sheaves usuallyplaced at the upper inner sides of said frame for the sash cords to runover are dispensed with and my two rollers hereinafter described areemployed instead. The window frame A is provided with the usual upperand lower slidable sashes B and C, respectively.

he. upper sash B is normally held in raised position by sash cords l and2 and sash weights 3 and 4. The sash weight 4 is, preferably, heavierthan the weight 3 for a purpose which will herelnafter appear.

receive the screw eyes 7 when the sash B raised to the end of its upwardmovement. The ends ofthe roller 6 are journaled in brackets 12 and 13,which latter has two cheeks 1,4 and 15. The cheek .14 has a Cir- I cularopeiiing l? toallowthe adjacent endof the roller 6 to extendtherethrough and. the cheek l5has a small hole 18 in which the: trunnion19 of the roller 6 is journaled. The brackets 12 and'13 have extensions20. and

attheir lower ends which are driven into the window frame A and thusreliably hold said brackets in'positionh- 23 designates an actuatingcord for pull., ing the sash B is wound around the roller 6 and has itsinner end attached either'to the lower end] of the sash cord 2 or theupper endof the 6 weight 4, while its outer portion runs over a campulley 25 mounted in abracket 26 secured to the inner face. of thewindow frame A. The lower end of the actuating cord 23, is preferably,attached to an orna; mental tassel 27 which affords a convenient gripwhen operating said cord 23. By making the weight 4 larger than theweight 3 it not only coacts with said weight 3 in overbalancing the sashB to normally hold it in raised position, but also holds the actuatingcord 23 taut and prevents its coils from getting loose on the roller 6,while the plate 145 through which the right end of the roller 6 extendsprevents said coils from shifting to the right far enough to get caughtbetween the right end of said roller 6 and the cheek 15 ofthe bracket13.

The counterweights 28 for the lower sash O, are only heavy enough tohold said sash atany point to which it may be raised or lowered by handin the usual way. Said counterweights 28 are secured to the lower endsof sash cords 30, extending upward to a roller 32 around which they arewound, and thencedownwardly through slots 31 and are attached to thetopof said sash C by downwardly. Said cord 23180 7 suitable means such asscrew eyes 83. The roller 32 parallels the roller 6, and like the sameis journaled at its ends in the brackets 12 and 13. y In practice thelower sash C is raised'and lowered in the usual manner, but the uppersash B is lowered by pulling downward upon the outer portion of theactuating cord 7 23, or its tassel 27. This operation rotates the roller6 and through the intermediacy of the cords 1 and 2 raises the weights 3and 4: and permits the upper sash B to descend. After the upper sash Bhas descended to the desired point it is held at such point by the camroller 25 which coacts with its bracket 26 in gripping the actuatingcord 23 and preventing it from moving upwardly. To raise the sash it isonly necessary to release the actuating cord 23 from between the roller25 and its bracket 26, whereupon the weights 3 and a, being heavier thanthe sash, raise the same through the intermediacy of the cables 1 and 2.

While my device can be used to advantage on average size sashes such asare used in residences, it is of especial advantage when applied tolarge wmdows such as are used in oflice buildings and the upper sashesof which under ordinary circumstances are difficult to gain ac ess to,owing to their height, for the purpose of raising or lowering saidsashes.

- From the foregoing it is apparent that I have produced a devicewhereby upper sashes may be easily and quickly operated and whileI haveshown and described the preferred form of my invention, I reserve theright to make such changes in the construction, combination andarrangement of parts as properly fall within the spirit and scope of theclaims. I

Having thus described my invention, what Copies of this patent may beobtained for I claim and desire to secure by Letters Patent, is:

1. In combination with a window frame and a slidable sash thereto, aroller journaled at the upper portion of said frame, overbalancing meansto normally hold the sash in raised position, cables wrapped around theroller and attached at their ends to said over-1 balancing means and thesash, an actuating cord wrapped around the roller and attached at itsinner end to one of the cables and hav: ing its opposite end dependingadjacent the inner side of the window frame, the overbalancing means ofthe last named cable exerting greater tension than the, overbalancingmeans of the other cable so as to hold the cord taut, a cam roller overwhich the outerv portion of the actuating cable runs, and a bracketsecured to the window frame to carry said cam roller and coact therewithin securing the actuating cable in position to hold the sash open.

2. In combination with a window frame having an opening in a sidethereof and having a slidable sash, a roller journaled in the frame top,overbalancing means, cables wrapped around the roller and connected tosaid overbalancing means and to the sash, an actuating cord engaged withthe roller between the cord ends to rotate the lOl'lGl' and having oneend connected to one of the cables and having its other end extendingthrough said opening in the side of the win dow frame and extending onthe inner face of the latter, and means to hold said co-rdj againstmovement.

In testimony whereof I aflix my signature, in the presence of twowitnesses.
